WHAT IS CGC SIGNATURE SERIES? The CGC Signature Series label (yellow) is applied to comic books that have been signed by someone of significance to the comic, under the direct observation of a CGC employee or select CGC authorized witness.

The signatures are then authenticated by CGC with the labels indicating who signed the book, the date it was signed, and in some cases the location of where it was signed. After the comic book or comic magazine is signed in the presence of a CGC employee or CGC authorized witness, the book is immediately submitted to CGC for grading and encapsulation in CGC's patented, tamper-evident holder, to become a treasured part of your collection. W ILL THIS D AMAGE MY BOOK?

This is an occasional effect produced by the inner and outer cases being in direct contact with one another. The visual effect is similar to oil on a water puddle because of the two plastics. If you gently separate the two pieces or insert a piece of paper in the side of the case, this should remove this effect. Ultimately it is not anything that is in direct contact with your comic, nor will it affect the comic's condition over time. All signatures were obtained by me at conventions/private sign ings or through a reputable 3rd party company (like Dynamic Forces) and come with a Certificate of Authenticity. Ungraded signed books no longer qualify for CGC signatures series as they are no longer in the possession of a CGC witness or employee. PLEASE CHECK O UT MY OTHER AUCTIONS.
